THE problem of correcting the aberrations inherent in electron lenses is of major importance particularly in the field of the electron microscope, where they set a limit to the resolving power. It ...

AN article by K. Spangenberg and L. M. Field (Elec. Comm., 21, No. 3; 1943) describes and discusses the measured characteristics of a number of electrostatic lenses, giving the characteristic ...

FIB-SEM is based on a scanning electron microscope, which provides a focusable beam of electrons scanned onto a sample with electrostatic and electromagnetic lenses. As charged particles, the ...

The JSM-IT800 uses an objective lens hybrid that combines an electron detection system through the lens with electromagnetic and electrostatic lenses. For sample analysis and EBSD imaging of magnetic ...

Electrostatic adsorption is an important complement to mechanical filtration for high-efficiency air filtering in the use of face masks. However, the electrostatic charge of the filters decays ...
